Fall Flowers Are Important for Pollinators and Birds



Despite my best efforts to support monarch butterflies, this year was discouraging: I only saw two monarchs visit my gardens. I have a small bed just for milkweeds, both the common one and swamp milkweed (Asclepias incarnata). But no monarchs laid eggs there this summer, no larvae ate the leaves, and I saw no butterflies sampling the nectar.
 
I know the importance of food for migrating monarchs at this time of year. They need to fill up on carbohydrates, fats and protein before flying long distances. That holds true for birds, too. Right now I have plenty of flowers blooming for monarchs and other pollinators, and seed heads waiting for the birds. I’m a bit discouraged, too, by the lower numbers of birds I am seeing. Let’s take a look at some of my fall favorites that migrating creatures could be feasting on.  
 

Blue stemmed goldenrod or Solidago caesia grows in shade

According to Doug Tallamy, the guru of native plants for pollinators, the number one plant we should all have is golden rod – and we probably all do. There are dozens of species of native goldenrod, all popular with bees, moths and butterflies. Many gardeners pull them out when they show up uninvited. A few species spread by root and can take over a flower bed – but others are clump-forming. Even if you don’t want them in your beds, think about leaving them at the edges of your fields or woods.

 
Of those species easily found for sale in garden centers, the best is Soldidago rugosa ‘Fireworks’. This plant is 3 to 5 feet tall, and stays in an ever-expanding clump in full sun or part shade, but does not take over. Its blossoms last a long time, the stems curving gently outward, like fireworks. And no, goldenrod does not cause hay fever – that is ragweed, which blooms at the same time.
 
Less common is blue-stemmed or wreath goldenrod (Solidago caesia). I bought a plant 20 years ago and it is blooming now in dry shade. It really has not expanded its reach very much. It grows just 1- to 3-feet tall, but usually is about 18 inches for me. It has delicate flowers that help light up a dark spot.
 
New York ironweed (Vernonia noveboracensis), is a tall native plant in the aster family with purple blossoms. It is still blooming for me, a month after starting to bloom. It does this by producing lots of buds which open sequentially – so it is not always a dramatic flower in a vase. But the bees love it. It is happiest in full sun in moist soil, but there it got too big for me, so I moved mine to dry soil with only morning sun. Now it is more manageable, but still a big plant. I’ve read that if you cut it back to the ground when it is 2-feet tall, it will stay smaller – but I never remember to do so. Sigh.
 
Speaking of asters, there are many native species, all good for pollinators and loved especially be monarch butterflies. This year the woodland asters are quite dramatic. They are a pale lavender, and grow in shady places. Elsewhere a taller wild cousin stands 4 to 6 feet tall with deep purple or pink flowers. These grow in full sun and are often seen by the roadside at this time of year. Asters of all sorts are readily available at garden centers. Ask for native ones, not fancy hybrids.
 

Joe Pye weed ‘Gateway’ blooms longer and better than wild forms

Joe Pye weed (Eutrochium purpurea) is another tall plant in the aster family. It can get huge – over 6-feet tall if grown in rich, moist soil. A named cultivar called ‘Gateway’ has longer lasting flowers and richer colors than the wild ones, though those are nice, too. Smaller varieties such as Little Joe, Baby Joe and Phantom are nice, and better suited for smaller gardens. I haven’t grown them but see they are sold as being 3- to 4-feet tall. Monarchs and other pollinators love them. All appreciate soil that does not dry out.

 
One tall annual that monarchs love is Brazilian verbena (Verbena bonariensis). It grows tall stalks that are remarkably tough – they grow 4 or 5 feet tall, but rarely need staking. Its flowers are in small clusters. It often drops seeds which send up new plants the following year.
 
Lastly for pollinators, I have to recommend fall crocus – which is not a crocus at all, but a Colchicum. This is a bulb plant that flowers on a six-inch stem (actually the throat of the blossom) in pink, white or lavender. It sends up foliage in the spring that dies back, then each bulb sends up a cluster of blossoms in September, or even earlier. They do best in full sun and rich soil, but do fine with some shade. They like to be fertilized each year. I often see small bees and wasps buzzing around in the blossoms.
 

Colchicum or fall crocus

I know that many gardeners are already cutting back their flowers in preparation for winter. But hold on! Flowers with lots of seeds can be left as winter snacks for our feathered friends. Among the best are black-eyed Susans, purple coneflower, sunflowers, zinnias, Joe Pye weed, coreopsis, sedums and ornamental grasses. Wait until spring to cut those back so that finches, chickadees, cardinals and other seed-eaters can enjoy them, especially on those cold, snowy mornings when you don’t want to go fill up your feeder.

 
And of course, leaving some work for spring means less work now! So leave some seeds for the birds, and enjoy watching them in the winter.

Sharpening Pruners



Fall is a good time to prune deciduous trees and shrubs. Once the leaves have dropped you can see the form – and the clutter – and decide what to take out. But before you begin, think about sharpening up your pruning tools, replacing blades, or buying new ones. Dull pruning tools are like dull kitchen knives: they’ll do the job, but not very well.
 

This sharpener is embedded with industrial diamond chips and costs under $10

How tough is it to sharpen your own pruners?  It’s really not that difficult. The biggest problem people have is overcoming their initial fear of ruining their tool by doing it wrong.  You need to learn the proper angle, have the proper sharpening tool, and the patience needed to do it right. Experience will tell you if you have done well, and you won’t ruin those Felcos (the most common brand of by-pass pruners out there) even if you don’t get it quite right the first time. It’s fun, once you get the hang of it.

 
What do you need for sharpening tools? The best sharpeners for hardened steel tools are made using synthetic monocrystalline diamonds embedded in nickel. I like the diamond sharpeners because they are very efficient. As a rule, five to ten minutes on a conventional oilstone is equal to about a minute with a diamond sharpener. Coarse files are fine for most pruners, while fine files are better for scissors and knives that are kept very sharp.
 
What’s the first thing you need to do when starting off? I clean the pruners, which usually are covered with dried sap and dirt and sometimes rust. You can use soap and water, but I prefer a product called Sap-X. I let it work for 30 seconds and then scrub the blades – first with coarse steel wool and then, after reapplying the solvent, with a green scrubbie or fine steel wool to get the rust. If you don’t clean your pruners prior to sharpening, all of that debris will end up clogging your sharpener.
 

Felco pruners come in various sizes

Then what? Grasp the pruner in your left hand (if you are right-handed), holding on to the handle that extends to the cutting blade. The cutting blade is the one that moves when you open and shut the pruners, and is the only one that you need to sharpen. Steady it by placing the pruner on the edge a table. Working under a bright light helps, because it will help you to see the shiny edge that develops as you sharpen.

 
Start sharpening as near to the throat of the pruners as you can (where the two handles join). Place the narrow tip of the tapered file at the throat, and push the file away from you, sliding it down the length of the beveled edge. With practice you will be able to use the full length of the file as you run it down the blade.
 
How will you know if you are sharpening at the correct angle? What you’re trying to do is restore the edge of your pruners to the original angle set when it was manufactured. Before you start take a magic marker and “color” the steel on the beveled edge of the moveable blade. This will help you to see what you’re doing – you want to remove the marks evenly across the beveled edge with your sharpener. If only a small portion of the blade turns shiny, you need to change the angle of your file slightly.
 
How much pressure should you apply on your sharpening tool? Not much – let the diamonds do the work. Sharpening will feel awkward at first, but gets easier as you do it. Use nice slow even strokes.
 
If you don’t have pruners, buy the best ones you can afford. If you take care of them, they will outlast you. Yes, you can buy some that look like good for $10, but the quality of the steel will not be the same as buying good ones. Plan on spending $50 or more. If you can try them out before buying some, -or use a friend’s pruners- that would help you make a good choice. They all come in various hand sizes, and some are right or left handed.
 

These Bahco pruners are French made and my favorties

I have tried many kinds of pruners, but my favorites are made by Bahco, a French company. I’ve had some for 20 years that have a good ergonomic design and will cut branches up to 1.25 inches in diameter. I got mine from a company in Massachusetts, OESCO (1-800-634-5557 or www.OESCOinc.com).

 
And what if you can’t seem to get sharpening right, then what? I’m sure with a little practice you’ll get it right!  But good pruners have replaceable blades, so if you’ve been cutting steel fencing with your pruners and ruined them, you can buy a new blade.
 
A replacement blade for a pair of Felco pruners (which cost $60 or more new) only costs about $20. Changing a blade requires a few basic tools, some common sense, and less than 5 minutes of work. And you need to look carefully at your pruners to see which model you have. Felcos have a number on the stationary blade, depending on the model you have, anywhere from 2 to 12.
 
As a last resort, look in the Yellow Pages under “Sharpening Services” and you should be able to find someone to do it for you – and maybe even show you how to do it yourself next time.

Invasives: What are they? What can you do about them?



I’m lucky. Unlike many houses built in the 1800’s or early 1900’s, mine had no invasive plants when I bought it in 1970, probably because it was built as a Creamery, or butter factory. Decorative plants were not needed. Most older houses are plagued with plants brought from Asia or Europe by well-meaning people who did not know that once imported, those handsome plants might not have any predators that could keep them under control. Most of our native insects will not eat foreign plants.
 
Plants including Japanese knotweed, Asian bittersweet, goutweed, purple loosestrife, yellow pond iris and multiflora roses have thrived in New England – and all are nearly impossible to get rid of, once established. Unfortunately, I now have four of the six mentioned above. But no Japanese knotweed or bittersweet, thankfully (they are two of the worst).
 

Multiflora rose hips are eaten by birds but the plants are invasive and should be removed.

Multiflora roses just showed up on my property last year, probably by birds that dropped seeds. It is easy to see roses growing in your woods or fields, or even in a garden bed and pass it by as “just a rose”. But the roses we love don’t just appear.

 
The multiflora rose was introduced from Asia in the 1860’s as a vigorous ornamental rose and as a source of rootstock for grafted roses. In the 1930’s it was widely introduced as erosion control and alongside highways – a mature planting is so dense it can prevent cars from going over median strips. But the birds liked the rose hips – their seed pods – and it escaped cultivation.
 
So what am I doing to eliminate it on my property? I am digging it out. Most effective for one or two year old plants, I am using a curved, single-tine hand tool called the CobraHead (www.Cobrahead.com) to carefully excavate the roots until I can lift the plant out.
 

Multiflora rose roots radiate out from the central stem

First, I dress appropriately: jeans, long-sleeved shirt, a hat with a brim, and heavy winter leather work gloves. This culprit wants to hurt anyone trying to uproot it. I cut off the branches, just leaving a foot or so to grab onto when pulling it out. Then I loosen the soil and pull weeds around it. The roots radiate outward from the stem like spokes on a bike. I loosen each root and tug gently when they are small enough to remove.

 
I do not burn brush anymore because of global warming, and don’t want any errant seeds to escape, so I cut up the branches and brought them to our town recycling center. I put them into the trash going to the landfill, along with the roots. It took me about an hour to remove and cut up one plant – and I have several. But this plant can grow 10 feet or more in a year, and strangle trees or shrubs.
 

Girdling buckthorn twice with a pruning saw will slowly starve it to death

I’ve read that just cutting back the stems to ground level will stimulate the roots to send up new shoots everywhere, causing a bigger problem. There is no easy answer. Invasive plants are always difficult to remove – usually a scrap of root can generate a new plant – or several.

 
Buckthorn is another invasive that is common along streams and at the edge of fields. Like multiflora rose, cutting it down stimulates the roots to send up new shoots. The best way to eliminate it is to starve the roots: Take a pruning saw and cut through the bark and the green layer of cambium beneath that. Go all the way around the trunk, then repeat six inches above the first cut, and repeat. This will not kill the tree until the third year, but this slow death will not stimulate the roots to grow. Best done in winter or fall after leaf drop.
 

Buckthorn often grows with several stems in a tight grouping

Since buckthorn are often multi-stemmed, it can be difficult to use that method. Do it up high enough that you can get your saw in between the stems. But I’ve done it, and it works.

 
Purple loosestrife is blooming now in swamps and wet places – it is gorgeous, but outcompetes many of our native wetland plants that feed pollinators and other animals. Like many invasives, it produces huge numbers of seeds and these seeds don’t all germinate the next spring – many stay dormant for years. I’ve read that multiflora rose seeds can stay viable up to 20 years – a good reason to clear plants out when young.
 
My approach to purple loosestrife is to dig out new, young plants. I recognize them by their square stem, the leaf shape and the color of the stem which is often reddish. But for big established plants I just use a curved harvest knife to slice off the foliage once or more than once each summer. This prevents seed production, and reduces plant energy.
 
As regular readers of this column k now, I only use organic techniques in the garden. This means no chemicals including herbicides. From what I have read, most herbicides will not kill the invasives mentioned in this article. They will set them back considerably, depending on the age of the plant and the dose of the chemical. But learning to recognize all the invasives is best. And if one appears on your landscape, get rid of it immediately! And remember, persistence is important

Gardening Better As We Age

Posted on Tuesday, September 5, 2023 · Leave a Comment 



Sedum ‘Autumn Joy’ is a reliable and easy perennial

As a Certified Senior Citizen I sometimes wonder if I am too ambitious in my garden. I have about an acre of gardens with 200 or more kinds of flowers and a good-size vegetable garden. These gardens please me greatly, and I visit them daily all year, even in winter. In gardening season I spend considerable time weeding, pruning, mulching and admiring our gardens. I am blessed with a wife who loves to garden, and even loves weeding and edging!

 
Still, I know that my body will not always be able to work as hard as I ask it to now. So what can we do as we get older to make our work easier? First, we can stop buying new plants and creating new garden beds when our current beds are full. That is a hard choice to make, but I do my best to follow that rule.
 
We can also diminish the size of our gardens. For years I have grown 35 to 50 tomato plants each year. But I will try to drop down to 25 next year, and a few less each year after that. I do love the tomatoes and freeze and dehydrate many each summer for year-round use. But we do have plenty of farm stands growing great veggies, and I could use them more.
 

Daylilies are easy to grow and require little work

Raised beds make gardening easier on us, too. I have one nice deep cedar gardening “trug” that is six-feet by two and a half-feet in size and stands 30 inches tall. I got it from Gardeners Supply several years ago and it has held up well. I grow mostly kitchen herbs in it, along with a little lettuce and a few hot peppers. It is just steps from the house, while the vegetable garden is downhill and a few hundred steps away. I might get another, or build one.

 
I recently visited my friend Fred Sullivan, a retired dairy farmer, who lives nearby. His wife of many decades, Shirley, passed away last year; she did most of the vegetable gardening but Fred has taken it on. Some years ago he made Shirley four nice raised beds using landscape timbers. Each is 4 ft by 8 feet and about 20 inches tall. He grows tomatoes, cucumbers, summer squash and some Swiss chard.
 
I asked Fred about his gardening efforts. He told me that the doctor said he needed to stay active if he wanted to stay healthy. Gardening is a good form of gentle exercise for someone in their 80’s, and you get “free” food, too! His best advice: “Be good to your soil, and it will be good to you.”
 
The raised beds make it easier to work. If you want raised beds, many companies are producing easy-to-assemble beds that are reasonably priced. Although most require quite a bit of soil mix, you can re-use the soil from year to year. I add fresh compost and some slow-release fertilizer each spring to my raised beds.
 

Sydney and her dog, Phoebe

I recently called my friend Sydney Eddison at her home in Connecticut to talk about gardening as we get older. She is the author of many gardening books and a few nice small books of poetry in recent years. Her book, “Gardening for a Lifetime: How to Garden Wiser as You Grow Older” (Timber Press, 2010) if full of good ideas.

 
Sydney told me, “Cultivate imperfection.” She said that as we get older we have to accept that our gardens can never be perfect. But she emphasized choosing plants that are reliable under any conditions, and that are low maintenance plants. I agree.
 
Delphinium and peonies, for example, are wonderful plants but most need to be staked and looked after to keep them from flopping or breaking in a heavy rain. I can’t imagine ever getting of my peonies, but maybe I don’t need quite so many – I could share a few with younger friends.
 
A plant that Sydney loves is a sedum called ‘Autumn Joy’. She has a dozen or so mature plants, each clump 30 inches wide, and they look good even in winter wearing what she calls “snowy hats”. Daylilies are also wonderful – and a mainstay in her garden. She pointed out that they can bloom for nearly 2 months if you pick early, mid-season and late season varieties.
 
Shrubs are less work to maintain than perennials or annual flowers. Plant them, or have someone plant them, and they will require little – so long as they are not varieties that grow inordinately fast. There are plenty that can go several years without pruning.
 
One of my favorites is called fothergilla (Fothergilla major). It has nice white bottle-brush blossoms in May and spectacular fall foliage. Mine, after 20 years and very little pruning, is only 5 or 6 feet tall and wide. It’s hardy to Zone 4.
 
And of course, the easiest plant to grow is lawn grass. Once established it really only requires a weekly mowing. There are plenty of people who are willing to do the mowing for a reasonable fee – and there is little they can do to damage it.
 

Sydney Eddison’s book is full of good advice for aging gardeners

Sydney Eddison gave me good advice: if someone offers to help in the garden, accept! And if no one does offer, try to hire a younger person to help. Offer to teach them about gardening and both of you will be happy. At the end of the day sit in the garden and drink tea and eat homemade cookies. Both of you will be happy.
